    Abstract: Systems and methods may place a battery in a first constant voltage charging mode and monitoring a diminishing current of the battery while the battery is in the first constant voltage charging mode. Additionally, the battery may be placed in a constant current charging mode when the diminishing current falls to a first predetermined threshold. In one example, a rising voltage of the battery is monitored while the battery is in the constant current charging mode and the battery is placed in a second constant voltage charging mode at an end of the charge cycle in response to the rising voltage reaching a second predetermined threshold. Moreover, a charge current corresponding to the constant current charging mode may be adjusted based on a charge capacity of the battery.

    Abstract: In an embodiment, an apparatus includes a battery shaped to be situated within a housing. The battery has a shape that substantially conforms to a shape of a cavity that is defined at least in part by a non-cylindrical curved portion of the housing. The battery includes a contoured conductive mesh formed by shaping a substantially planar conductive mesh to include at least one curved conductive mesh portion. Other embodiments are described and claimed.

    Abstract: A system and method for automatic session data transfer between computing devices based on zone transition detection are disclosed. A particular embodiment is configured to: determine if a mobile or wearable computing device is located within a proximity zone around a location of a stationary computing device; establish an authorized wireless data connection with the mobile or wearable computing device via a wireless transceiver; determine if the mobile or wearable computing device is likely departing the proximity zone and if so, upload user session data to the mobile or wearable computing device; and determine if the mobile or wearable computing device is likely approaching the stationary computing device and if so, download user session data from the mobile or wearable computing device.

    Abstract: Li-metal battery with a pressure chamber to allow uniform pressure on a battery. The pressure chamber is supported by metal plates (such as pressure equalization plate) used to give uniform pressure to the battery. The pressure chamber may include pressured gas, elastic material, spring plate, etc. The outer skin of the pressure chamber is free to bow, restrained at its edges by (metal) skin, but still exerts a uniform pressure on the plate that is compressing the battery cell. The pressure chamber gives uniform pressure to battery, which is used to enable high-energy density battery with, for example, 20% more battery life.
